Breaston has MRI on knee, could miss 1-2 weeks

Cardinals coach Ken Whisenhunt said he was satisfied with the way his team played in its 20-10 loss at Pittsburgh, but said there is a new concern: Steve Breaston's knee. Breaston had an MRI on Friday after the knee stiffened up following Thursday's game in Pittsburgh.

Whisenhunt said during a news conference Friday that he thinks Breaston fell on his knee at some point during the game and that the MRI results would determine whether Breaston misses any time. Safety Dennis Keyes suffered a leg contusion that will cause him to miss a week or two.
